The Rigi (or Mount Rigi; also known as Queen of the Mountains) is a mountain massif of the Alps, located in Central Switzerland. The whole massif is almost entirely surrounded by the water of three different bodies of water: Lake Lucerne, Lake Zug and Lake Lauerz. The range is in the Schwyzer Alps, and is split between the cantons of Schwyz and Lucerne, although the main summit, named Rigi Kulm, at 1,797 meters above sea level, lies within the canton of Schwyz. The Rigi Kulm Hotel, established in 1816, is located on the summit.

The Rigi Kulm and other areas, such as the resort of Rigi Kaltbad, are served by Europe's oldest mountain railways, the Rigi Railways. The whole area offers many activities such as skiing or sledging in the winter, and hiking in the summer.
